In order to optimize the shear resistance of polyvinyl alcohol fiber cement-based composites (pva-ecc). In this paper, four specimens with different roughness interfaces between pva-ecc and old concrete are tested and studied. Based on the uniaxial compression test, the shear strength of four interface specimens and their interface failure types are obtained. According to the test data, the ratios of the shear strength of the four specimens to the strength of the whole specimen are 18.95%, 27.27%, 45.48% and 92.2% respectively.
